If you're looking for an endless supply of 2D character and background images for your animations then Artbreeder, an online Artificial Intelligence (AI) that generates image mash-ups you can tweak as much as you like, could be the ultimate content library.

What is Artbreeder?

Artbreeder is free to use though there are various paid plans, that give you additional features, such as higher resolution download images or more settings to play with. All images created on the site are Public Domain (CC0 License) and can be used in commercial projects.

Using Artbreeder's online app you can generate head shot portraits, full body characters, landscapes, and other scenes simply by choosing two or more existing images to mash together then, using a series of sliders, to select which traits from each image you wish to lean toward in the final image.

You can choose from existing source images on the site or, in some categories, upload your own. 

I found it interesting to upload my own photo headshot because Artbreeder does not use the literal image uploaded. Instead it recreates an approximation of the image, using its AI, ready for use in the app. My recreated image looked slightly more youthful.

I'm not going to go into a detailed tutorial on how to use Artbreeder. It takes a little experimentation to work it out but, once you do, it can be fun just seeing what kind of images you can generate. It seems like there's a slider adjustment for almost everything, ranging from art style, to age range and more.

Turning Artbreeder images into an animation

I thought I'd experiment to see if the images I produced could be brought into Reallusion's Cartoon Animator 4 and turned into an animation.

My plan was to create a simple animation showcasing the background and a character.

Below are my two original downloaded images created with Artbreeder. I was trying to generate a kind of steampunk fantasy character with a background to match. Following that is my final demonstration animation and the run down for how I put it all together.

Note, if you're using Artbreeder, and see an image you kind of like but aren't sure, click and save it anyway. There's no real undo feature, and restoring a single setting back to what it was is no guarantee you'll get the previous images back.

Preparing the images

Obviously my Artbreeder images were not ready to be loaded straight into Cartoon Animator. I needed to rig my character and break up my background into layers so I could create a parallax effect.

To prepare my images I used Krita, the free, open source image editor.

The background I split into three layers, the foreground rocks, the mid ground city, and the background sky. I did do some work to fill in the sky behind where the city was in the image but not too much since the parallax scrolling I wanted to create would be very subtle and the scale of the city would mostly hide the gap in the sky.

The female character I broke up into the various body part layers. I then exported a G3, front facing dummy character from CA4 into Krita in order to get the right character template. Next I copied all my body parts into the relevant layer folders in the template.

I saved a separate image of the characters head to use for the morph based head (which is the fastest character head to rig in CA4).

With regard to the character I didn't create a full set of hand sprites or create bone hands, since this is just a demo animation. I did create an extra set of flipped hand sprites so the character could fold her arms without her hands looking wrong.

Bringing the images into CA4

My background image I saved as a photoshop file (.psd) and simply dragged it across onto CA4's stage area, importing it as a scene. CA4 retains all the layer information so, once the image was on the stage, I just moved each layer on the Z axis in order to create the parallax, depth I was going for.

I did add two 'fog' props to my scene from Reallusion's Weather Maker pack just to give the scene a little more atmospheric perspective (If you don't have this pack in your CA4 library I highly recommend it as an essential purchase).

My female character was also saved as a .psd file. I simply dragged the same dummy character I used to get the template in Krita onto the stage, went into the CA4 character composer, and imported my girl template.

All that remained to do then was create the morph based head using the head composer tools.

Turning it all into an Animation

The background set required very little animation as the parallax effect is created by the movement of the camera - which I keyframed to go from a wide shot to a mid shot of the girl.

I did animate a slight horizontal drift to the fog but you barely notice it unless you really watch closely once the camera stops moving.

The girl's walk toward character utilizes CA4's new Import 3D Motion feature for G3 characters. All of the front facing walks I had in my content library for 2D characters looked too cartoony and awkward (I can't imagine any of them look good, even with cartoony characters). So I imported a 3D motion of a female walking along a catwalk, and it was such a vast improvement.

When the girl stops, moves from side to side, and crosses her arms, that is part of an existing 'Idle Stand' motion from Reallusion's G3, 2D motions, included when you buy the software.

The girl's face and head animation is a little erratic and random because I just couldn't be bothered keyframing all her expressions. Instead I fired up the Motion 2D Live plug-in for faces and motion captured my own face. I'll admit it's not my best work but it kind of does the job for a thirty second demo.

Finally I added some cinematic music from YouTube's creator library, ambient desert wind sounds, and cinematic black bar letterboxing.

In Conclusion - Is Artbreeder any good as an image library for animation?

My demonstration animation certainly has its fair share of things that could be improved. Particularly my morph based head which could be so much better with a lot more time and effort (as well as my face capture acting). I mention this just to say those things are not down to Artbreeder's usefulness.

If you're willing to upgrade to Artbreeder's subscription plans you'll have an endless supply of high resolution images (the free plan is limited to about five high resolution downloads). Even on the free plan there are many more features than I've covered here.

Most of the portrait and character images are front facing which could be an issue as there's no way to create alternate views of a character you've saved. Or even the same character with different outfits (though you could solve this by rigging your character's head onto different outfits).

Most of the backgrounds are landscapes or abstract at this stage. Great for creating other worldly scenes but you'll need to look elsewhere for interiors. The interiors in the 'General' category didn't seem all that useful for creating actual interior background scenes.

I don't think I'd use Artbreeder as a source of graphics for a commercial project due to its limitations but there's a lot of fun to be had tinkering around with it on the side.

I could see myself definitely using it to generate backgrounds for certain projects - particularly anything that needed other-worldly landscapes or city skylines.

It's definitely fun experimenting with the range and types of characters you can generate. Everything from photo realistic humans to furries and anime.

While you can certainly use the characters in your projects I'm not so sure how flexible (or time saving) they might be if you needed multiple angles of your character rigs. Certainly there's a lot of fun to be had generating a bunch of characters and animating them in smaller one shot style projects.

Overall Artbreeder is a useful tool that, if nothing else, could be a great starting inspiration point for your animated projects, and may be a good way to generate some of the final art too.


Note: I am not affiliated with Artbreeder and this post is my honest impressions of the site based on my experience creating the demo animation.

The Ultimate Independent Animator's App and Resource List 2019-2021 - Animation and Video Life

Image created with Cartoon Animator 4. Being an independent animator is not like a studio animation job. There's so much more to do that is indirectly related to the actual task of animating. Over the years I've sought out many apps, tools, and services that can help me achieve that one single task, expressing myself through animation. Below is my Ultimate Independent Animator's Resource List for 2019. It started out as a list of free or low cost apps that could help you in every stage of producing either 2D or 3D animation, and then just kind of grew from there. You may not have been looking for a Time Management App as much as you needed something to get you started in 3D animation but when those commissioned projects start coming in you'll have a head start on maximizing your time. All the apps and services on this list had to meet two main criteria: They had to be useful and relevant to an Indy Animator/artist. The base app/service had to be US$200.0

Make Disney/Pixar Style Characters with Reallusion's Character Creator and Toon Figure Bases

The Extraordinary Tourist Classic Coat outfit created using Reallusion's Toon Designer for CC3. I've talked before how I've wanted to get into 3D Disney/Pixar style character animation since I first saw the animated cutscenes for the very first Tomb Raider game back in 1996. It's why I initially bought Reallusion's iClone 3D studio app as soon as I could afford a computer that would run it. But then Reallusion released their 3D Character Creator (CC) for iClone and I wanted to create my characters with that (and I did try with Bat Storm ). But the focus of CC was realism, even with ToKoMotion's stylised body morphs . Now with Reallusion's Cartoon Designer bundle for CC3 which features two packs, Toon Figures , and Toon Hair , designing Disney/Pixar style 3D characters just got a whole lot quicker. The two packs are the bare essentials for creating Toon style characters. Five body morphs (2 male, 2 female, and one adolescent body morph that w

Three Image Overlay Apps. Do More with Your Reference Images While You Work

PureRef's image overlay in action with Cartoon Animator 4. One thing Cartoon Animator 4 still does not have in stage mode is the ability to onion skin previous and next frames.  For those complete animation newbies among you, onion skinning is the ability to see through the current frame to your previous and/or next keyframes so you can see the progression of your character or object's movement as you create and adjust each keyframe. Usually the previous and next frames appear lighter so your current frame remains the key focus. This prompted me to look for a tool that could overlay an image over my work to use as a reference while still allowing me to work on the app underneath the overlay. I had seen, and even used such apps in the past but it had been some time so I decided to see what was out there, preferably free and/or open source, with versions for Mac and Windows. Overlay 2 There are actually a number of apps that do nothing more than overlay an image but the only one

Run Your Favorite Android Animation Productivity Apps (and Games) on Your PC or Mac with BlueStacks

BlueStacks Android Emulator for PC or Mac. There are many free and low cost mobile animation productivity apps for Android in the Google Play Store that would fit right into your workflow if you could access them directly from your PC/Mac  desktop (or laptop) computer. Even if those apps can save their output to the same cloud storage you use with your PC or Mac, just the divide of using a separate device makes them inconvenient and disruptive. Worse yet, what if your Android device is underpowered for the apps you want to use, or worse still you don't own any Android devices because someone convinced you Apple Mac's, iphones, and ipads are 'cool' (they are, but you pay for 'cool'). BlueStacks is a free, open source Android emulator for Windows or Mac (currently only BlueStacks 4 can be installed on a Mac but BlueStacks 5 for Mac is coming soon). If you're not aware of what an emulator is, it's basically a piece of software that mimics another devices

Stylish Stick Figures for Cartoon Animator 4.2 - New Characters by TET

Stylish Stick Figures by TET. Animating stick figures is almost a right of passage for any animator who has ever made an old fashioned flipbook or discovered the free stickman animator app, Pivot Animator . There's also the hugely popular viral stick figure animation, Animator Versus Animation  and its sequels by Alan Becker that continue to inspire variations more than 12 years later. Back when Vyond was GoAnimate they had a stick figure theme that was popular site wide despite having many other themes with much more refined Saturday morning cartoon style characters. I even had my own stick figure series, Harry Chalk , on GoAnimate. Long story short, I was looking through the Reallusion Cartoon Animator Marketplace and discovered there really weren't any well designed, traditional looking stick figure characters. That's not to say there weren't any at all but I wanted something similar to GoAnimate's stick figures which included full facial features and male and

Review: CrazyTalk Animator 3 vs Moho Studio Pro 12

Reallusion's CrazyTalk Animator 3 or Smith Micro's Moho Studio Pro 12. Which of these 2D animation applications is right for you? Regular readers of this blog will know I'm a strong supporter, and fairly proficient user of CrazyTalk Animator since version 1. It's a great piece of software for producing 2D animations from purchased content quickly and, with version 3, is easier than ever to create animations from your own art. Lesser known is that I first purchased Moho Studio Pro 12 (then known as Anime Studio Pro 9) back in October of 2012 and have been upgrading it to the latest version ever since because I believed in it as an application for creating great 2D animation to TV quality standard. As such, it's a much more complex application than CTA3 that I only got around to learning properly late last year. I'm still in the process of blogging my progress . Despite this I feel I've learned enough of Moho to compare it to CTA3 to help you determ
